本文介绍了截断变量MATLAB的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在使用MATLAB中的数组A
.此数组中的值最多包含5个小数.我想将这些值截断为更少的十进制数.
I'm working with an array A
in MATLAB. The values in this array have up to 5 decimals. I would like to truncate those values to a less number of decimal.
有没有办法做到这一点?
Is there a way to accomplish this?
谢谢!
推荐答案
由于某种原因,Matlab的"truncate"函数称为fix
.所以
For some reason, Matlab's "truncate" function is called fix
. So
>> fix(3.5)
ans = 3
>> fix(-3.5)
ans = -3
要将任何内容截断,舍入,舍入或舍入到小数位数,请乘以数十次幂,截断,舍入,舍入或舍入到ceil,然后将结果除以数十次幂.
To truncate, round, floor, or ceil anything to a given number of decimals, multiply by powers of tens, truncate, round, floor, or ceil, and then divide the result by powers of tens.
所以:
>> fix(123.456 * 10^2)
ans = 12345
>> ans / 10^2
ans = 123.45
